Methods for polishing flooring surfaces

ABSTRACT

A method for treating a surface of flooring includes applying a composition that includes a silicate to a surface of the flooring and, while the composition is present on the surface, polishing or burnishing the surface. The silicate may be a lithium polysilicate and/or a colloidal silica. The composition may further include a surfactant and/or a leveling agent. When the composition is applied to the surface of the flooring, gravity may enable it to spread substantially evenly across the surface. The acts of applying and polishing or burnishing may be repeated. Such a treatment may result in a surface that has a glossiness of at least 80, as measured by a gloss meter set to a 60° angle of incidence.

TECHNICAL FIELD

The present invention, in various embodiments, relates generally to compositions and methods for protecting and polishing substrates and, more specifically, to compositions that include a silicate, such as an alkali metal polysilicate (e.g., lithium polysilicate, etc.) or a colloidal silica. In particular, the present invention relates to compositions that include a silicate and one or more siliconates, or organosiliconates, as well as to the application of such compositions to flooring surfaces. In a specific embodiment, the present invention relates to a composition that includes lithium polysilicate and a siliconate, such as a metal siliconate or, even more specifically, an alkali metal siliconate. Such a composition may, in some embodiments, be applied to flooring surfaces, in connection with polishing or burnishing the flooring surfaces.

RELATED ART Use of Alkali Metal Silicates on Inorganic Substrates

Alkali metal silicates, such as potassium polysilicate and sodium polysilicate, have long been used to protect, harden, and polish inorganic substrates, such as cement. When applied to an inorganic substrate, alkali metal silicates react with free lime (calcium oxide, calcium hydroxide) in the inorganic substrate to prevent the surface of the inorganic substrate from becoming porous, or to reduce porosity at the surface of the inorganic substrate.

Over recent years, lithium poly silicates, which are also known in the art as “lithium silicates,” have found widespread use in a variety of compositions that are formulated for application to inorganic substrates, such as concrete, masonry, and stone. Compositions that include lithium silicates may be formulated for a variety of purposes, including to protect, densify or harden, and/or polish the inorganic substrates to which they are applied.

The ever-increasing use of lithium silicate in connection with inorganic substrates has been due, in part, to its superior performance in penetrating and reacting with inorganic substrates when compared with other alkaline metal polysilicates, such as potassium polysilicates and sodium polysilicates. Among other things, lithium silicate is less alkaline (i.e., has a lower pH) than other alkaline metal silicates, which protects the substrate from undesirable reactions and improves the stability of the substrate. It has also been found that lithium silicate penetrates more quickly and further into inorganic substrates than other alkali metal silicates (possibly due to its smaller size than other alkaline metal polysilicates), further enhancing the ability of lithium silicate to protect the inorganic substrates to which it is applied against staining and deterioration (such as that caused by wear, dusting, sweating, efflorescence, scaling, surface alkali silica reaction (ASR), damaging alkalis, etc.).

While alkali metal silicates protect the surfaces of inorganic substrates by hardening and densifying the surfaces to which they are applied, they are typically not used to seal the surfaces of the substrates to which they are applied. Instead, thicker polymeric coatings are used for that purpose. While polymeric coatings on inorganic flooring surfaces provide protection for extended periods of time and may initially increase glossiness, they are scuffed and scratched over time, particularly in high traffic areas.

Alternatively, or in addition to a polymeric coating, inorganic floor surfaces may be protected by use of a wax, particularly when a high gloss finish is desired. When wax is applied to an inorganic floor surface, it is typically applied in several (e.g., three to seven) relatively thick coats. But, like any other protective coating, when subjected to traffic, the protective coating that has been formed by the wax is scratched and scuffed.

As the number of scratches and scuffs in any protective coating increases, the gloss of the protective coating decreases. In order to maintain the desired level of glossiness, the protective coating must be periodically burnished, which consumes significant amounts of time. When a wax is used to protect the inorganic flooring surface, periodic burnishing requires the use of organic solvents, such as butoxy ethanol, which are often harmful to the environment, as well as to the persons who use such solvents. In some settings, wax coatings are burnished on a daily basis, requiring significant time and resources (e.g., burnishing pads, butoxy ethanol, etc.).

In addition to the undesired maintenance that wax and other protective coatings require, they must also be stripped and replaced periodically. In high traffic settings, such as stores, schools, and hospitals, wax protective coatings on floors are often stripped and replaced every six to eight weeks. Due to their thicknesses, wax protective coatings must be stripped to prevent undesired buildup of the wax. Stripping requires the use of hazardous organic solvents, such as butoxy ethanol, and consumes a great deal of time, as the old wax must be collected and discarded. Frequent reapplication of wax protective coatings also consumes valuable time and resources (e.g., wax, burnishing pads, etc.).

DETAILED DESCRIPTION

The present invention includes compositions for protecting the surfaces of inorganic substrates. In some embodiments, compositions of the present invention may also impart inorganic substrate surfaces with a polished finish. One embodiment of such a composition includes water, a silicate, acrylic latex, an alkaline metal methyl siliconate, a silane coupling agent, and a solvent.

The following table lists various components that may be included in various embodiments of a composition according to the present invention, as well as possible amounts of each component of such a composition:

Percent Percent (weight/weight) (weight/weight) (Specific Component Range Embodiment) Water Balance 68.95 Solvent (e.g., Ethylene 0.25-1   0.5 Glycol Monobutyl Ether, (Ethylene Glycol Dipropylene Glycol Monobutyl Ether) Dimethyl Ether, Dipropylene Glycol n-Butyl Ether, etc.) Leveling Agent (e.g., Fluoro 0.05-1   0.05 Surfactant, Silicone (Silicone Leveling Leveling Agent, Trialkyl Agent) Phosphate, etc.) Silane Coupling Agent 0.5-2.5 2.0 (e.g., N-β (aminoethyl)-r-aminopropyl- trimethoxysilane, etc.) Silicate (e.g., Lithium 10-25 16.0 Polysilicate, etc.) Alkali Metal Methyl  1-7.5 2.5 Siliconate (e.g., Potassium Methyl Siliconate, etc.) Acrylic Latex  4-25 10.0

All weight percentages in the preceding table and elsewhere throughout this disclosure account for the total weight of each component, including water.

While other components may be included in some embodiments of a composition that incorporates teachings of the present invention, other embodiments consist essentially of water, a silicate, acrylic latex, a siliconate, a silane coupling agent, and a solvent, with the surfactant being a non-essential component. In other embodiments, a composition of the present invention consists of water, a silicate, acrylic latex, a siliconate, a silane coupling agent, and a solvent, while a surfactant, such as a fluorosurfactant, may be required in still other embodiments of a composition of the present invention.

In various embodiments, the solvent of a composition of the present invention may be a glycol solvent, such as ethylene glycol monobutyl ether. Ethylene glycol monobutyl ether is also known as “2-butoxyethanol” and as “Glycol Ether EB.” It has the molecular chemical formula C₆H₁₄O₂ and the chemical structure CH₃CH₂CH₂CH₂OCH₂CH₂OH. Ethylene glycol monobutyl ether is a solvent for a variety of resins, including, without limitation, acrylic resins. As a solvent, ethylene glycol monobutyl ether enhances wettability of a composition of the present invention. Ethylene glycol monobutyl ether is available from a variety of sources, including the Dow Chemical Company of Midland, Mich.; Eastman Chemical Company of Kingsport, Tenn.; and Lyondell Chemical Company of Houston, Tex.

Other examples of solvents that may be used in various embodiments of compositions according to the present invention include, but are not limited to, dipropylene glycol dimethyl ether and dipropylene glycol n-butyl ether. Dipropylene glycol dimethyl ether has the chemical formula CH₃OCH₂CH(CH₃)OCH₂CH(CH₃)OCH₃ (major isomer). The Dow Chemical Company sells dipropylene glycol dimethyl ether under the trademark PROGLYDE™ DMM. The chemical formula of dipropylene glycol n-butyl ether is C₄H₉O[CH₂CH(CH₃)O]₂H (major isomer). Dipropylene glycol n-butyl ether is available from The Dow Chemical Company under the trademark DOWANOL® DPnB.

A silane coupling agent of a composition of the present invention may have at least two reactive groups of different types bonded to a silicon atom in the molecule. One of the reactive groups (e.g., a methoxy group (—OCH₃), an ethoxy group (—OCH₂CH₃), a silanic hydroxyl group (—SiOH), etc.) is reactive with an inorganic material, while another of the reactive groups (e.g., a vinyl group (—CH═CH₂), an epoxide (in which an oxygen atom is covalently bonded to two adjacent, covalently bonded carbon atoms, forming a three-member ring), a methacryl group (CH₂═C(CH₃)C(O)—), an amino group (—NH₂), a thiol or mercapto group (—SH), etc.) is reactive with an organic material. These two reactive groups of the silane coupling agent bind inorganic components (e.g., the silicate, etc.) and organic components (e.g., the siliconate, etc.) of a composition of the present invention to each other. It is also believed that the two reactive groups of the silane coupling agent enhance adhesion of a composition of the present invention to an inorganic substrate. In addition to its binding and potential adhesive properties, the silane coupling agent may serve as a sealant and/or as a water repellant.

In a specific embodiment, the silane coupling agent of a composition of the present invention may comprise or consist of an aminoethyl aminopropyl trimethoxy silane (C₈H₂₂N₂O₃Si), which is known by the chemical names N-β(aminoethyl)-r-aminopropyl-trimethoxysilane, [3-(2-Aminoethyl)aminopropyl]trimethoxysilane, and N-[3-(Trimethoxysilyl)propyl]ethylenediamine. Such a material is available from Dow Corning Corporation of Midland, Mich., as Z-6020, as well as from a variety of other sources.

The silicate of various embodiments of a composition of the present invention comprises an alkali metal silicate, such as lithium polysilicate. In alternative embodiments, the silicate may include an alkali metal polysilicate, such as potassium polysilicate and/or sodium polysilicate, and/or a colloidal silica in place of or in addition to the lithium polysilicate. Silicates are available from a variety of sources. For example, Grace Davison, a subsidiary of the Grace Performance Chemicals division of W.R. Grace & Co. of Columbia, Md., sells lithium polysilicate under the trade name LUDOX®. Various silicates are also manufactured by PQ Corporation of Malvern, Pa.

Silicates, which are inorganic materials, may impart a cured or solidified form of a composition of the present invention (e.g., a coating, etc.) with a desired hardness, which may further prevent abrasion or impact damage to the inorganic substrate. Silicates may also chemically react with components of some inorganic substrates to further enhance the hardness that the silicates otherwise provide. As an example, silicates may chemically react with various materials of inorganic substrates, such as the free lime within concrete.

In addition to imparting a composition of the present invention with hardness, a silicate may provide some water repellency, as well as minimize or eliminate corrosion of an inorganic substrate to which the composition is applied (e.g., on which a coating that comprises a cured or solid form of the composition is formed, etc.).

Further water repellency may be provided by the siliconate of a composition of the present invention. In some embodiments, the siliconate may comprise a metal siliconate, such as an alkali metal siliconate (e.g., potassium methyl siliconate and/or sodium metal siliconate, etc.) all of which are manufactured by Dow Corning. In a specific embodiment, the siliconate of a composition of the present invention consists of the potassium methyl siliconate available from Dow Corning as XIAMETER® 0777. In such embodiments, the composition lays out, or spreads, well. Thus, there may be no need for a leveling agent (e.g., a fluorosurfactant, etc.) in such embodiments.

Acrylic latex is an emulsion of an acrylic polymer in water. In a composition of the present invention, acrylic latex may facilitate adhesion of the composition to an inorganic substrate. In a specific embodiment, the acrylic latex may have a solids content of about 47% to about 49%, such as the PLIOTEC® PA90 acrylic latex available from Eliokem of Villejust, France. Another example of a latex that may be used in various embodiments of compositions according to the present invention is AVANSE™ MV-100 from The Dow Chemical Company.

In embodiments of compositions that include surfactants, nonionic fluorinated surfactants, or “fluorosurfactants,” may be used. Fluorosurfactants are more effective than ionic (hydrocarbon) surfactants at reducing the surface tension of water and, thus, the surface tension of a composition in which they are included. The reduced surface tension of a composition that includes one or more fluorosurfactants may facilitate wetting of a substrate surface with the composition, as well as spreading and leveling of the composition on the surface of the substrate. The inclusion of a fluorosurfactant in a composition of the present invention may also enable a composition of the present invention to penetrate smaller voids in a substrate than may be penetrated by embodiments of compositions that lack fluorosurfactants (i.e., that include other types of surfactants or that lack surfactants). A specific embodiment of a composition of the present invention includes the fluorosurfactant marketed as MASURF® FS-120A by Mason Chemical Company of Arlington Heights, Ill. In another specific embodiment, a composition of the present invention may include a fluorosurfactant and comprise a short chain molecule (e.g., four carbon atoms, etc.), such as the perfluorobutanesulfonic acid-based fluorosurfactants marketed by 3M of St. Paul, Minn., under the trade name NOVEC™.

As an alternative to a surfactant, or in addition thereto, a composition according to the present invention may include a leveling agent of a type known in the art. Like surfactants, leveling agents enable a composition of the present invention to wet and smoothly coat a substrate and, in the case of substrates that are formed from porous materials, to penetrate the substrate. One example of a leveling agent is the silicon leveling agent available from Dow Corning under the trade name DOW CORNING® 2-9034 Emulsion. Another example of a leveling agent is trialkyl phosphate, such as the tris(2-butoxyethyl) phosphate having the chemical formula C₁₈H₃₉O₇P available from Chemtura Corporation of Philadelphia, Pa., as KRONITEX® KP-140 (“KP-140”).

In addition to acting as a leveling agent, KP-140 may reduce or eliminate foaming as a composition that incorporates teachings of the present invention is compounded and/or used. When relatively small amounts (e.g., less than about 0.3% w/w, about 0.2% w/w, about 0.1% w/w, etc.) of KP-140 are used in a composition of the present invention, the composition may harden more quickly than, and may reduce soiling better than, compositions that include relatively large amounts (e.g., about 0.3% w/w, more than about 0.3% w/w, etc.) of KP-140.

The following EXAMPLES identify components of some additional specific embodiments of compositions that incorporate teachings of the present invention.

EXAMPLE 1

Percent Component (weight/weight) Water 39.99 Dipropylene Glycol n-Butyl Ether 1.00 (e.g., DOWANOL ® DPnB from The Dow Chemical Company) Silane (e.g., DOW CORNING Z-6020 ® 3.81 from Dow Corning Corporation) Lithium polysilicate 30.20 Potassium Methyl Siliconate 5.00 Latex (e.g., AVANSE ™ MV-100 from 20.00 The Dow Chemical Company)

The composition of EXAMPLE 1 may be applied directly to an inorganic substrate or it may comprise a concentrate that may be diluted with water before application to an inorganic substrate. In a specific embodiment where the composition of EXAMPLE 1 comprises a concentrate, it may be diluted with water at a ratio of 1:1, by weight or volume, before application to an inorganic substrate. The resulting diluted composition hardens quickly (more quickly than the composition of EXAMPLE 3), but it takes about twenty-four (24) hours to about thirty-six (36) hours from application and drying on the surface of an inorganic substrate before the resulting film and, thus, the surface of the substrate resists standing water.

EXAMPLE 2

Percent Component (weight/weight) Water 53.364 Trialkyl Phosphate (e.g., KRONITEX ® 0.3 KP-140 from Chemtura Corporation) Dipropylene Glycol n-Butyl Ether 0.7 (e.g., DOWANOL ® DPnB from The Dow Chemical Company) Silane (e.g., DOW CORNING Z-6020 ® 1.916 from Dow Corning Corporation) Lithium polysilicate 16.32 Potassium Methyl Siliconate 2.4 Latex (e.g., AVANSE ™ MV-100 from 25.0 The Dow Chemical Company)

When the composition of EXAMPLE 2 is applied to an inorganic substrate, it may resist standing water within about thirty (30) minutes after it has dried. The composition of EXAMPLE 2 flows and levels on the surfaces of inorganic substrates better than the composition of EXAMPLE 1, with less streaking than the composition of EXAMPLE 1, making the composition of EXAMPLE 2 easier to apply than the composition of EXAMPLE 1. It remains relatively soft for about four (4) or five (5) days, however.

In another aspect, the present invention includes embodiments of methods for blending compositions that are useful for protecting inorganic substrates. One specific embodiment of such a method includes mixing water and a solvent, optionally adding a leveling agent to that mixture, then adding a silane coupling agent, a silicate, a siliconate, then acrylic latex. In an even more specific embodiment, the surfactant and/or leveling agent may be “sweated” into the water. Sweating may include mixing using high shear agitation, in a manner known in the art. Sweating may be effected for a sufficient period of time for the surfactant and/or leveling agent to be completely dissolved and/or homogeneously dispersed throughout the water. In some embodiments, the surfactant and/or leveling agent may be sweated into the water for a period of about thirty (30) minutes. In embodiments where a solvent is used, the solvent may also be sweated into the water and into any previously included component (e.g., a surfactant, a leveling agent, etc.). As with sweating a surfactant and/or a leveling agent into water, the process of sweating a solvent into water or an aqueous solution or suspension may include mixing or agitation, and may be effected for a sufficient duration to enable the solvent to completely dissolve and/or be homogeneously dispersed throughout the water.

In addition, the present invention includes methods for protecting inorganic substrates. An embodiment of a composition according to the present invention may be applied to the surface of an inorganic substrate (e.g., by spraying, etc.) then spread (e.g., with a microfiber mop, etc.). The composition may be applied in one coat or in a plurality of coats.

In some embodiments, the surface of the inorganic substrate, with the composition thereon, may then be polished or burnished in a manner known in the art (e.g., with a diamond-impregnated pad, etc.). In embodiments where more than one coat of the composition is to be applied to a substrate, the surface to which the composition is applied (and the composition on that surface) may be polished or burnished after each application.

In a specific embodiment, a composition of the present invention is applied to a surface of an inorganic substrate (e.g., concrete, terrazzo, ceramic tile, etc.). The composition may be sprayed and/or spread onto the surface of the inorganic substrate. The surface of the inorganic substrate may then be burnished, particularly where the inorganic substrate comprises a floor. The application and/or burnishing processes may be repeated at least once. Such a process may protect the surface of the inorganic substrate, as well as provide it with a polished finish.

When such a process is employed, each layer of the coating may have a thickness of about 5 μm to about 6 μm or less, which may be significantly thinner than a layer of wax. The glossiness of the coating, which may be measured with a gloss meter of a type known in the art in terms of light reflected at an angle of incidence of 60° on a surface of the substrate, may be up to about 80% or more.

When applied to a floor that is subjected to moderate to heavy levels of traffic, a coating of a composition of the present invention may have a useful life of at least six months, and may last for as long as two years or more, as opposed to a useful life for wax of about six weeks with frequent (e.g., daily, weekly, etc.) burnishing in high traffic areas. Due to its hardness, a coating of the present invention may retain its shine and exhibit little or no wear over the life of the coating. If desired, however, a coating of the present invention may be burnished from time to time, without the requirement of environmentally unfriendly chemicals, such as the butoxy ethanol that is typically used when waxed flooring surfaces are burnished.

At the end of its useful life, a coating of the present invention need not be stripped from the surface of an inorganic substrate, as is required when wax is used. Due to the thickness (or, rather, thinness) of the worn coating(s), another coating may simply be applied atop the worn coating(s). When such a technique is used, the new coating will have substantially the same appearance (e.g., glossiness, etc.) as the original coating. By eliminating the need to strip the worn coating, the use of environmentally unfriendly chemicals is avoided, as is the mess (e.g., clumps of old wax, etc.) that is typically associated when conventional protective coatings are stripped from substrates (e.g., waxes from floors, etc.).

Although the foregoing description contains many specifics, these should not be construed as limiting the scope of the present invention, but merely as providing illustrations of some embodiments. Similarly, other embodiments of the invention may be devised which do not exceed the scope of the present invention. Features from different embodiments may be employed in combination. The scope of the invention is, therefore, indicated and limited only by the appended claims and their legal equivalents, rather than by the foregoing description.
